the patio/fire escape stairs to the second floor (and the escape ladder to the ground floor), and

the roof hatch.

Once on the third floor, there are two other doors:

The south door from the third floor elevator landing, and

the east gate from the third floor elevator landing.

There are also a basement and a roof which are off-limits.

Front Gate

Connects To: Outside, Front Door.

The front gate is an iron gate with an electronic latch driven by the intercom pad next to the north stairwell door. This door uses a Spark brand lock. The lock uses a Kwikset-style ward with pins 73655 (tip to shoulder.) We share this lock with our neighbors on the 2nd floor and the landlord.

Front Door

Connects To: Front Gate, North Stairwell Door, Elevator.

The front door is a pair of glass doors, each with a lock near the floor to drive a pin into the ground. Both cylinders use Schlage-style wards with pins 42466 (approx.)

North Stairwell Door

Connects To: Front Door, Elevator, Noisebridge.

This door uses generic Schlage compatible wards and uses the standard Noisebridge version A key.

Elevator

The elevator takes about 33 seconds to go between the first and third floors, while walking at a normal pace up the stairs takes about 20 seconds. Thus, the stairs may be used more often than the elevator for members without bicycles.
